149544 ÷ 7 
The aim is to understand the frequency of 7 in 149544.

Going ahead to step 1:
7 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 7

Moving on to step 2:
If we divide 14 by 7, we get 2 and a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 14 from 14 and we're left with 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 7

Let's proceed to step 3:
9 divided by 7 is 1 with a remainder of 2.
The next digit of our result is 1. 
Result so far: 21.0
The remainder is 2 after subtracting 7 from 9.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 7

On to step 4:
25 divided by 7 is 3 with a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 213.0
If we take 21 away from 25, we end up with 4.
Grab the next digit (4) from the dividend, add it to 4, then carry on: 44 / 7

On to step 5:
44 divided by 7 is 6 with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 2136.0
Subtracting 42 from 44 leaves us with 2.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 7

On to step 6:
The number 7 fits into 24 3 times, leaving a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 21363.0
If we take 21 away from 24, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
The number 7 fits into 30 4 times, leaving a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 21363.4
Subtract 28 from 30 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
7 can be fit into 20 2 times, resulting in a remainder of 6.
The next digit of our result is 2. 
Result so far: 21363.42
If we take 14 away from 20, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 9:
7 can be fit into 60 8 times, resulting in a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 21363.428
The remainder is 4 after subtracting 56 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 10:
The number 7 fits into 40 5 times, leaving a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 21363.4285
Subtract 35 from 40 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 11:
7 can be fit into 50 7 times, resulting in a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 21363.42857
Subtracting 49 from 50 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 12:
The number 7 fits into 10 1 times, leaving a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 21363.428571
If we take 7 away from 10, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 13:
7 goes into 30 4 times with a remainder of 2.
The next digit of our result is 4. 
Result so far: 21363.4285714
Subtracting 28 from 30 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 14:
When dividing 20 by 7, we get 2 with a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 21363.42857142
Deduct 14 from 20 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final result is 21363.42857142 with a remainder of 6e-09.
